Transform Plate Boundaries: Sliding Plate Tectonics …

Deformation mechanisms are commonly characterized as brittle, ductile, and brittle-ductile. The driving mechanism responsible is an interplay between internal (e.g. composition, grain size and lattice-preferred orientation) and external (e.g. temperature and fluid pressure) factors. These mechanisms produce a range of micro-structures studied in rocks to constrain the conditions, WebCreep Mechanism: Grain Boundary SlidingReference:"Animation: Grain Boundary Sliding Creep", V.

Boundary sliding

Grain boundary sliding (GBS) is a material deformation mechanism where grains slide against each other. This occurs in polycrystalline material under external stress at high homologous temperature (above ~0.4 ) and low strain rate and is intertwined with creep. Homologous temperature describes the operating temperature relative to the melting temperature of the material.
